Description：Ho-tae and Dong-hee grew up together like brothers. Ho-tae, who moved to Seoul a few years ago, returned to Gangneung after his father's funeral. On the other hand, Dong-hee was kicked out of the house for coming out, and lived alone in Ho-tae's empty house. The two who met again after a long time began to live under the same roof. When Dong-hee saw Ho-tae, who was like a brother and her first love again, although he wanted to control his excitement, it was not easy. Ho-tae also developed feelings for Dong-hee, whom he had not seen for a long time, that he had never had before. In order to escape from his chaotic feelings for Dong-hee, Ho-tae began to date girlfriends casually. Dong-hee felt hurt seeing Ho-tae like this, and the precarious relationship between the two began to slowly change because of an unexpected incident...
